Quantum critical detector: amplifying weak signals using discontinuous quantum phase transitions. [PDF]
Optics Express, 2018 We propose a quantum critical detector (QCD) to amplify weak input signals. Our detector exploits a first-order discontinuous quantum-phase-transition and exhibits giant sensitivity (χ ∝ N2) when biased at the critical point.

Analysing weak orbital signals in Gaia data
, 2014 Anomalous orbits are found when minimum-chi^{2} estimation is applied to synthetic Gaia data for orbits with astrometric signatures comparable to the single-scan measurement error (Pourbaix 2002).

Cosmological information in Gaussianised weak lensing signals
, 2011 We investigate the information on cosmology contained in Gaussianised weak gravitational lensing convergence fields. Employing Box-Cox transformations to determine optimal transformations to Gaussianity, we develop analytical models for the transformed ...

A NOVEL APPROACH TO WEAK SIGNAL PROCESSING [PDF]
Information and Telecommunication Sciences, 2013 A novel effective approach to weak continuous and digital signals processing in communication channels with high noise levels is proposed and investigated. The essence of proposed approach is illustrated by examples of various electronic devices. The conditions which allow obtaining the maximal gain in signal to noise ratio are found. This gain exceeds

ANALYSIS OF TSUNAMI-MAGNETIC ANOMALY SIGNAL IN INDONESIAN REGIONS USING THEORETICAL APPROACH AND RECORDED MAGNETOGRAM [PDF]
Science of Tsunami Hazards, 2020 The flow of conducting ocean water generates weak magnetic signals relative to the main field. These signals lead to magnetic anomaly observed as variations in the vertical component b! z of time- varying secondary field and the horizontal component b! H

Detection of Weak Signals Under Low SNR Stochastic Resonance System
IEEE Access, 2023 To solve the problem that weak signals are difficult to detect accurately in low signal-to-noise ratios, this paper presents a method to achieve effective detection of weak signals, applying the method of stochastic resonance to bistable systems.

Algorithm Used to Detect Weak Signals Covered by Noise in PIND
International Journal of Aerospace Engineering, 2019 Detection of the loose particles is urgently required in the spacecraft production processes. PIND (particle impact noise detection) is the most commonly used method for the detection of loose particles in the aerospace electronic components.

Via@In this article, we focus on recreational practices that explicitly mobilise references to "nature," either here (in urban spaces) or nearby (in the urban environment). "Urban trails" and "micro-adventures" are two examples.
